这个题目很简单呀,35%的订单是35岁以下订阅者定的,同时又说绝大部分订单是35岁以下的定的。只有一个可能,那就是统计的POLL不一样呀。唯一的可能就是一些人看了杂志但是没有订杂志,换句话说,就是传阅呀!!!

这个解释很清楚

this problem features QUANTITATIVE DATA. that may make you grimace, depending on your mindset about quantitative data, but it shouldn't: all you need to do is look for the discrepancy in the numbers, and then find an answer choice that accounts for the discrepancy. unlike problems that are all words, these problems feature discrepancies that will essentially jump out at you if you examine the numbers.

when you examine the numbers, you must also pay close attention to DIFFERENCES, especially SLIGHT categorical differences, between categories that are being compared. in this problem, the most important difference is between subscribers who order and people who order. (there's also the distinction between random orders and orders in response to ads, but that distinction isn't tested, because both surveys are on the same side of it.)

in this problem:
of the orders placed by _subscribers_ in response to ads, only 30% were from the under-35 crowd.
of the orders placed by _anyone_ in response to ads, over 50% were from the under-35 crowd.
there's the discrepancy.

therefore, you need an answer choice that explains where all the extra orders in the 'anyone' category. this means in the 'anyone category and not in the 'subscribers' category; no more, no less. that's exactly what is described in choice e.

我觉得是这样:举例比较容易理解。。。假设广告商收到了1000份订单,800份都是35以下的童鞋订的,这是从广告商的survey里得出来的一种情况,再假设订杂志的人力总共有300人下订单,其中有100个下订单的人是35岁以下,200个是35岁以上,这样就能解释了,广告商的1000份订单里,35岁以上的童鞋有200个,剩下还有800个35岁以下的,其中100个是自己花钱定了杂志的,还有700个童鞋是蹭别人杂志看的,所以就能解释E了。。。不知道这个解释合理不。。。

设订单的所有下单人集合设为O(100%),由第一个调查知道30%的下单人满足条件:subscriber,response to advertisement  and under 35. 由第二个调查知道大多数(假设为80%)下单人满足条件:response to advertisement and under 35。所以有50%下单人不是subscriber的人。

解题方法:
ABCD都没有关系,一眼看去E唯一相关

实际理解:
Finding1-30%订阅杂志的是35岁以下
Finding2-大多数(>60%)购买杂志的是35岁以下
-〉购买杂志的人里有很多没有订阅
(但一开始看真的很绕......超级绕......)

这道绕人的题干是这样的
1 调查杂志订阅者:30%的货单是由35岁以下的订阅者看了S杂志广告下的单
2 调查在杂志上登广告的商家:看了S杂志上的广告下单的大多数人年龄在35岁以下

问支持或者加强

E是说许多人对那些S杂志广告上的货下单的人没有订S杂志

言下之意是不是说,S杂志广告只对年轻人有吸引力,跑偏了,大家讨论讨论吧,为啥是E,我也没绕的太出来
